also little suggestion could you add the "giant" versions of the class icons to the wave maker? (it serperates the small ones from the giants)

Giant versions of the class icons are just normal icons, but red if you have the MiniBoss tag selected.

i know its just the wave can be fixed visually (with a sensible giant amount when compared to non-giants)

Someone posted the solution how to deal with this. Open the .pop file and change name of the icons there from demo to demoman (or vice versa, i dont remember), along with changing heavy to heavyweapons (vice versa possible too). But really, taking time to fix this can take small time.
